Problems of Deploying JSF war file to Tomcat

Hi, I am a beginner in JSF. I created some web applications with JSF using Oracle JDeveloper. Thse are correctly running on JDeveloper's in-built oc4j. I deployed those applications on Tomcat and Jboss. Those are not working on non of those. I dont know the corrct url to be called for the web application running on tomcat or jboss. I tried my best according to the url's I tested on Oc4j.

I dont know whether it's possible to attch the war file with this forum. I have the WAR file with me, and it's correctly extracted in the webapps folder of the Tomcat 5.5.20. But in the Internet Explorer, it gives the HTTP Status 404 error message.
